Application tiled January 26, 1921.

To all 'whom it may concern.'

Be it known that l, Vieron R. WLLOGH- BY, residing at Ridgewood, Bergen County, New Jersey, and .being a citizen of the t United States, have invented certain new and usefullmprovements in a 'Tank-Ins1 chargevalve Mechanism, of which the fol#I lowing is a full, clear, and exact descrip tion, suoli as will enable others skilled in the art to which it appertains to make and to use the same,reference being had to the accompanying drawings, which illustrate thel preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modiiications thereof withinthe scope of the claims will occur to persons skilled in the art.

ln ,said drawings: Figure 1 is a vertical longitudinal Sectio taken on line 1-1 of Fig. 2 looking in the direction indicated by the arrow, and showing a preferred embodiment of my invention with the valve in lockedl closed position; l

Figure 2 is a lan view of the same; Figure 3 is a orizontal section taken on line 3--3 of Fig. l looking in the direction t0 indicated by the arrow;

Figure 4 is an elevational view of the invention showing the application thereof. to the bottom of a tank;

- Figure 5 is a view similar to Fig. 1 showing the valve in closed position but unlocked; and

Figure 6 is a view similar to Fig. 1 showing the valve in full opened position.

My invention relates to the class of outlet e0 valves employed in tanks used for the transportation of oil, asphalt and like commodities, and is of the type adapted to prevent extraction of tank contents except upon manipulation of certain valve controlling mechanism within Ithe tank.

Une object of my invention is to rovide means ore'ecting the positive loc ing of the valve upon .its seat through the medium of a reciprocating` valve supporting memserial no. 43am?.

bell' having telescopic engagement with said 50 va ve.

Another object is to provide means for permitting the valve to grind upon 'its seat prior to the locking thereof.

A further object is to protect the valve member of the device by so arranging the part associated with the valve member as to prevent the ingress of matter tending 'to congeal in'the space between said parts and to shield the interen aging threaded portions thereof froni the ad etl'ects of the tank till contents.

In said drawings, 10 represents a tank at the bottom of which is arranged the usual discharge outlet 1,1 with which is associated a housing 12 threaded into the outlet as shown at 13. Housing 12 is provided with a number of openings 14- for the egress of the tank contents and supports within its contines .a reciprocatory valve supporting 7o and locking member 15.

The valve supporting and locking member 15, while permitted to reciprocate within the housing 12, is held from rotation therein by means of the stud bolts 16 tapped into the housing 12. *The stud bolts 16 are each provided with protruding lingers 17 adapted to provide a loose or pin and slot connection between the housin 12 and valve locking member 15 throu h t e medium of slots 18 in the valve loc ing member into which slots said fingers 17 project.

`Within the valve locking member 15 is threaded a reciprocatory and rotatory valve member 19 having a disc portion 20 to fit upon valve-seat 21 and close discharge open-4 ing 22. The valve member 19 is shown with its disc portion 20 integral therewith but may, for greater convenience in manufacturing or assembling, be formed in separate parts and suitably tted together.

It will be noted that the valve lookin member 15 is chambered as shown at 23 and 24 and provided with contracted portion 25 screw-tapped to receive threaded portion 26 e5 of the valve member 19 and a contracted throat portion 27 adapted to engage valve member 19 with a neat fit.

dit

Resting upon valve member 19 and opera.- tively associated therewith is a shaft 28 eX- tendlng upwardly through an opening 29 in the valve locking member with which it engages at this point also with a neat iit. Shaft 28 is provided with a polygonal stud portion 30 entering the socket 31- of the valve member y19 for controlling the valve mechanism.

Assuming the valve to be in the locked closed position shown in Fig. 1, the shaft 28 is rotated to open the valve. During the initial period o'l rotation of said shaft, valve locking member 15, `by virtue of its threaded engagement with valve member 19 driven by said shaft, will i'all until the upper ends of slots 18 contact with engaging fingers 17 of the stud bolts 16 when its further descent will be checked, said stage of operation being shown in Fig. 5 of the drawings. During this period and range oit movement of the valve locking member 15 the reeiprocatory valve member 19,'though rotating with shaft 28, has not left the valve seat 21 but has been allowed to remainwith its disc portion 20 grinding therein.

Continued rotation of shaft 28. with further downward movement of valve locking member 15 arrested, will cause valve member 19 to rise, carrying with it disc portion 20 and shaft 28, and thread its way upwardly into chamber 23 of the valve locking member 15 to the full open position shown in Fig. 6.

Upon reverse rotation of operating shaft 28, the valve member 19 will first move downwardly, threading its way in the relan tively fixed locking member 15 until the disc portion 20 of the valve member rests in valve seat 21, at which time the relative positions of the parts at this stage of movement is as shown in Fig. 5. Continued rotation of the shaft and valve member 19 will cause valve disc 2O to grind in valve. seat 21, and the valve locking member \15, by virtue of its threaded engagement with valve member 19, to rise .under the influence of the rotating valve member 19 until the bottom ends of slots 18 engage the undersides of fingers 17 of stud bolts 16, at which time the downward pressure of the valve member 19 upon the valve seat 21 will have been translated into a pressure upwardly against the underside of fingers 17 through the medium of the inter-engaging threaded portions of the parts and the valve locked 1n the closed position shown in Fig. 1.

' From the operation of the mechanism as above outlined, it will be evident that at no time during the period of movement of valve member 19 and locking member 15 do said members have simultaneously reciprocal movements, but said parts will move successively.
